In regards to a career as a quant, the top firms may focus on "young geniuses" but there will be plenty of places where your profile would be just fine. It's a broad industry!
That's good to hear! if you could share more info about it I'm all ears
They get what they want.
But the question is what to do with that! haha
You don’t have to do that. Check out free resources like cs50x and freecodecamp

For what it's worth: I ended up going the quant/finance route (as a "regular guy" with no meaningful accomplishments). If I could start over I would try to do something involving data analysis and biology. I think RNA sequencing is on an exp(-a*t) cost curve, and it feels like this is a domain where data analysis could produce something of greater value than slightly more efficient asset prices.
I'm a bit afraid, like a bunch of people I guess, of AI eating all those data analyis/science jobs. But that field sounds definitely interesting.
